The new QD48 Family of dual output, 48 V input, DC-DC

converters from Power-One offers unprecedented per-

formance in a quarter brick package by providing two in-

dependently regulated high current outputs. This is ac-

complished by the use of patent pending circuit and pack-

aging techniques to achieve ultra-high efficiency, excellent

thermal performance and a very low body profile.

In telecommunications applications the QD48 converters

provide up to 15 A per channel simultaneously - 30 A total -

with thermal performance far exceeding existing dual quarter

bricks and comparable to dual half bricks.

Unique to quarter bricks, the QD48 converters utilize inde-

pendent power trains and control functions for each output,

allowing very tight output voltage regulation and very low

channel interference. In some applications they can be used

to replace two single-output quarter bricks.

Low body profile and the preclusion of heat sinks minimize

airflow shadowing, thus enhancing cooling for downstream

devices. The use of 100% surface-mount technologies for

assembly, coupled with Power-One’s advanced electric and

thermal circuitry and packaging, result in a product with ex-

tremely high reliability.

The QD48 family provides any combination of standard volt-

ages from 5.0 V to 1.2 V in an industry standard seven-pin

package. Outputs can be trimmed from –10% to +10% of the

nominal output voltage, thus providing outstanding design

flexibility.

The QD48 family is designed to be a drop-in replacement for

existing dual designs, and utilizes a common trim function for

both outputs. The converters are also available in a surface

mount package.

Inclusion of this new converter in new designs can result in a

significant reliability improvement over other available duals

because of its optimized thermal efficiency.
